# Domain checker

Run the bundled Python 3 checker without packages, credentials or a browser. Resolve `scripts/check_domains.py` relative to this SKILL.md, regardless of the working directory.

```sh
python3 <skill-dir>/scripts/check_domains.py example.com example.dev example.ai --json
```

Use complete domains, not bare brand names or URLs; expand each name/TLD combination. Only domains directly under a TLD are supported (e.g. `.com`, `.dev`, `.ai`, `.cloud`), not multi-label suffixes such as `.co.uk`.

The script discovers endpoints through IANA and queries public registries, not registrar shopping carts. Use small batches; concurrency is capped at 4 requests.
